Due to the nature of my co-op being new product development, I am under an NDA so can not illustarte any parts of my co-op. However I have found images from the internet that Illustrate similar ideas.

Wind Tunnel Assembly
Wind Tunnel Assembly
While on the Outdoor team I helped research, design, assemble and test a Wind tunnel to help test certain aspects of the Outdoor selection of products. Since these products are propane powered we must ensure that the flame will not be extinguished to meet Underwriters Laboratories (UL) certification. For this project What I did was
Designed, assembled, and tested wind tunnel that could reach 20+ MPH in an area of 5”x5”
Researched and wrote a Standard operating Procedure based on previous team knowledge and standard necessity
Created a table in Excel based on recorded data to Correlate location in tunnel to wind speed
Communicate with a cross functional team about the tunnel and how to use it

Centrifugal Fan Testing
Centrifugal Fan Testing
After Switching from Outdoor to Indoor, I started working on Air fryers and understanding how different fans from out array of Indoor oven Solutions work. This means being able to characterize different centrifugal fans based off their size, blade angle, working angular velocity, and Air flow rate. For this testing what I did was:
Designed, assembled, and tested a fixture that allowed quick interchange of fans for testing
Researched Fan laws to properly scale different fans, and minimize acoustic impact of fans
Created a table of 25+ different characterized fans to allow quick look up of Fans
Wrote a Standard Test procedure to characterize more fans so list can continue to grow

Radiation Shield Testing
Radiation Shield Testing
In the design of new Air fryer Products, the Radiation (Rad) shield is a pivotal part in creating the proper outcomes when it comes to food loads. The Rad Shield determines everything from how even the food cooking area is to the humidity inside to unit to something even as basic as the overall Heat loss inside the unit. What I did was:
Researched previous solutions from different in-house products and competitors’ units
Iteratively test representative Heat Proof models to test food loads on
Test Air speed in an array of locations inside unit to understand quantitative changes in average air speed
Research a list of levers and what changes positively or negatively impact food load results
